[Libunwind-devel] [PATCH 0/4] ARM enhancements

[Ken Werner]

Hi,

These patches improve the libunwind support on ARM Linux. The first patch 
implements the unw_is_signal_frame function to enable signal frame detection. 
The second patch implements support for parsing the .ARM.exidx and .ARM.extab 
sections. These sections contain the unwind information as specified by the 
'Exception Handling ABI for the ARM Architecture' document. The third patch 
adds UNW_ARM_METHOD_EXIDX as a new unwind method that uses the ARM-specific 
tables. The fourth patch implements a small unit test that uses the new 
libunwind internals directly - it may be dropped.

Zachary T Welch (4):
  Add ARM signal frame detection
  Add module for parsing ARM-specific unwind tables
  Use ARM-specific unwinding tables in unw_step
  Add test of backtracing using ARM-specific tables
